IMPROVEMENT IN DRAlN-PLOWS.

Specification forming part of Letters Patent N0. 20,639, dated June 29, 1858.

To all whom t may concern:

Be it known that I, Moses BAnRowMAN, of Buffalo, in the county of Erie, iu the State of New York, have invented a new and lmproved Drain-Plow; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention relates, iirst, to the construction of a center piece, which serves as a main frame or support for other parts of the plow; second, in the combination and arrangement ofthe several parts, as hereinafter more fully set forth.

To enable others skilled in the art to make and use my invention, I will proceed to describe the saine, the annexed drawings making a part of this specification.

Figure I is a side elevation of my said improved drain-plow, all the parts thereof being together ready for use. Fig. II is a plan of the same. Fig. III is an elevation ofthe ccnter piece, looking from the rear, showing the flanges. Fig. IV is an elevation of the colters, showing also a portion of the conveyer.

A represents the center piece. It may be made ot' cast-iron. Flanges are caston the upper edge for the purpose ofsupporting the conveyer, and also for the purpose ot' giving strength. These langes are shown at a a, Fig. III. Flanges are also cast on the bottom, for the purpose of holding the sole-shoe and for strength. This center piece forms the inain structure, to which the otherparts of the plow are connected.

B is a circular conveyer. It is supported upon the upper flanges of the center piece. It is made of sheet iron, and serves the purpose to convey the dirt which is loosened by the colters and plowshare up and out of the drain. As soon as the earth is cut by the colters and loosened by the plowshare it passes onto the conveyer, and the pressure or resistance of the hard earth in front ot' the colters is sufficient to force the loosened earth up the conveyer. It has sufficient elevation to raise and carry oft' the dirt. It should be made in sections, so that the parts nearest to the plowshare, and which are subjected to the greatest wear, may be replaced with new ones as often as i may be necessary. It gradually widens from its lower to its upper or discharging mouth, so as to prevent the dirt from wedging or clogging. The colters will cut the solid dirt line enough to prevent any larger lumps or slices from passing onto the conveyer than it is capable of receiving and conveying freely and without choking. ing it, if from further experience it shall be deemed expedient.

C is the sole plate or shoe. This may be made of cast-iron, or, if preferred, it may be made of wrought-iron. It is bolted onto the bottom flanges of the center piece, and as often as it wears out it may be thrown aside and a new one put in its place. It is made nearly as wide on the bottoni as the plowshare.

D is the plowshare. This cuts or loosens the earth horizontally and raises it to the couveyer. It should be made of the same width as the distance between the colters and of the required width of the drain. When worn out it can readily be replaced with a new one. The dotted lines show the nose of the center piece, on which the plowshare is iitted.

E is the bearing-wheel. This is connected to the center piece by two supporting-arms, in which arms it is made adjustable. The object of this wheel is to take alarge proportion of the weight of the plow, and thereby lessen the friction upon the soleshoe. It also serves a purpose in turning and in carrying the plow. It runs in the track otl the sole-shoe.

F F, Fig. IV, represent colters. These are supported on each side ot' the plow-beam in a manner common to ordinary plows, and cut the ground, so as to make both sides of the drain perpendicular. The colters will also prevent any slices, rods, or stones from passing into the conveyer of a larger size than will freely pass up the oonveyer.

Gr Gr, Fig. II, are adjustable and supporting wheels. These are connected to the shaft K bythe arms H. The arms H pass through slots in the ends of the shaft K, in which slots they are adjustable. A lever, J, is also connected to the shaft K, by which the wheels may be raised in the arc ot' a circle, (the shaft K being the center,) and thus the wheels have a double adjustability, and the thickness of the slice to be out by the plowshare can there- I also contemplate cover- A by be gaged. By means of a pin or bolt the ever may be fastened to the segment-plate I, and thereby the Wheels held in their circular adjustment, Where required. The shaft K is sufficiently long to allow the wheels to track on each side of the drain.

L is the plowhandle; M, brace, which con nects the plow-handles to the tail of the center piece, and by which the plow-handles are made adjustable; N, plow-beam; O, clevis; P, timbers, connecting plow-beam to vcenter piece.

I do hot claim either of the bearing or adjustable wheels herein described, nor the arms, levers, or shafts by which they are supported, when separately considered. Nor do I claim their' combination or arrangement differently MOSES BARROWMAN.
